A Graph-Theoretic Approach to the Jump-Number Problemc representation. Then, we strengthen the greedy algorithm and exhibit a class of posets for which it generates optimal linear extensions. Finally, we give a short informal survey of construction methods for arc representations of posets and a list of the most important contributions to the jump num
